Abstract (en)
[origin: EP1707846A1] In an automatic transmission 100 which performs connection and disconnection of rotational driving force between a crankshaft SI and a gearbox by means of twin hydraulic clutches including first and second clutches CL1 and CL2, the first and second clutches are disposed on the axis of the primary shaft SP back to back with a primary gear GP interposed therebetween. Oil passages 4 and 5 can be therefore formed into a more simple shape than those formed by a method in which twin clutches are accommodated in a single case and can be configured to have a same total length. The first and second clutches are of a same component. The first clutch CL1 CAN perform connection and disconnection for first and third speeds, and the second clutch CL2 can perform connection and disconnection for second and fourth speeds.
